Definitions

  • the invention relates to a method for manufacturing a ground-water flow restricting or sealing screen in the soil by introducing wide flexible sheets from the land level into the soil by connecting said elements releasably at least with their lower edge to a water pressure lance of substantially the same width, which sheets are introduced into the soil by said lance and after the disconnection of each sheet the lance is retracted after which a next sheet is connected to the lance and introduced into the soil such that a sealing is brought about between adjacent edges of the respective successive sheets.
  • Such a method is known from BE-A-627 142.
  • the flexible sheets are selfsupporting due to the fact that they are provided with edge profiles. Moreover as material metal has been mentioned. Said sheets are connected to a frame by clamping the lower edge of the sheet by means of springs against the horizontal leg of an U-shaped profile of the frame and by attaching the upper edge of the sheet by means of adjustable screws to the upper end of the frame. Said frame is made in the form of a water lance and each sheet is inserted into the soil by means of water jets. Each sheet is mounted to the frame of the water lance in the horizontal position of said frame. After mounting it has to be placed upright and guided downwardly but prior to doing this the profiled edge of each sheet has to be guided into the profiled edge of a sheet which previously has been placed into the soil. After the sheet has been lowered it has to be disconnected from the frame of the lance. To achieve this the sheet is raised by means of the adjustable screws so that the springs acting on the lower edge of the sheet press its lower edge outwardly away from the profile.
  • Purpose of the invention is to provide a method for manufacturing a ground water flow restricting or sealing screen which is simple and cheap and can be applied in several ways.
  • the flexible sheets are non self-supporting foils and that the sealing of adjacent edges between an already placed sheet and the next one is only brought about after the completion of the placing of said next sheet.
  • the more or less flexible sheets or foils which are applied according to this method can be formed from cloth which is impregnated with water retaining material, for instance a tar product, but preferably these elements comprise a sufficient rigid synthetic foil.
  • the non self-supporting sheet or foil according to the invention now can be introduced into the soil without paying any attention to guidance of its edge with respect to the edge of an already placed sheet.
  • the lance need not to be connected with the foil in a horizontal position. It is sufficient to connect the edge of a foil supplied from a role with the lower edge of the lance so that during feeding the foil into the soil by means of the lance the foil is unrolled from the supply.
  • the lance need not to have a frame able to carry the entire length of the sheet. The only requirement necessary is that the lance has sufficient length to be guided into the soil for the required depth.
  • DE-A-2 546 946 a method is known for manufacturing a water flow restricting or sealing screen, which method makes use of foils supplied from a role.
  • the foil is placed according to a certain sequence in a prefabricated slot filled with a wall supporting liquid, such as bentonite, which liquid after the replacement of the foils has to be replaced by a filling material, like sand or cement.
  • a wall supporting liquid such as bentonite
  • the lance After disconnecting the sheet according to the invention the lance is retracted after which the sheet remains in the narrow slot. This slot is closed by sinking against the sheet, which sinking can be stimulated when the lance is subjected to vibration during the retracting.
  • the once mounted sheet is able to accommodate the ground water pressure because the sheet is supported against the walls of the slot which is obtained by injection and closed after retracting the lance.
  • this can be realized by arranging the sheets or foils in overlapping position such that they seal upon each other by their overlapping edge faces with the edge face of each sheet over the edge face of the previous arranged sheet, which is turned towards the highest water pressure side.
  • An overlap of some decimeters, for instance 2 dm, is intended.
  • the sealing is brought about by the pressure of the ground and the ground water itself.
  • a more complicated solution can be obtained if downwardly directed bores are made in the soil according to the line of the path of the screen to be made, by drilling. or injecting, which bores are spaced at a distance which is substantially equal or smaller than the width of the sheets and at which each sheet is downwardly introduced into the soil by the lance connected thereto with the edges at the location of two succeeding bores, after which, at least in the bore in which are the edges of two succeeding sheets, hardening material is introduced. If one proceeds according to this method the edges of the sheets will be in the area of the bores. These edges can overlap each other, they can end a short distance from each other and they even can be provided with inflatable edge strips.
  • the sealing is brought about by introducing hardening material into the bores. This encloses the edges and ensures the sealing.
  • a method for making a screen into the soil according to which a frame comprising two spaced apart jets and interconnecting plates is guided into the soil during the injection of a hardening liquid which injection is continued during the redrawal of said frame. After withdrawal the material hardens and forms a screen.
  • This screen of course is made from cement or concrete.
  • the frame has a tube of large diameter and a tube of smaller diameter and in operation the tube of larger diameter is placed downstream. After the manufacturing of one part of the screen and removal of the frame it is reintroduced into the soil with the tube of small diameter guided into the concrete filled bore made by the tube of large diameter. This leads to problems at the end of a manufacturing period if the next day the work has to be continued.
  • a side edge strip is in continuing connection with this lower edge strip, so by filling a side edge strip of a recently mounted sheet, which overlaps a side edge of a preceding sheet, the lower edge is fixed simultaneously with the sealing and anchoring of these side edges.
  • edge strips With the application of inflatable edge strips it is further in many cases preferably to use edge strips of a material which is permeable for the hardening filling material. In this way is achieved that the hardening material penetrates into the surrounding ground and so improves the anchoring. Further an affixing to each other of the inflated side edges is achieved and with the application of vertical bores the filling of the bores is furthermore provided in this way or at simultaneously filling the bores and the side strips an intimate connection is produced.
  • the invention also relates to a lance for practising the method according to the invention at which lance the downwardly directed injection orifices of said lance comprise two parallel' long rows divergently injecting spray nozzles.
  • the lance can further be provided with spray nozzles which are directed upwardly, i.e. contrary to the downwardly directed double row.
  • a lance with a single row of spray nozzles can of course also be used.
  • the lance is at both sides of the downwardly directed double row spray nozzles provided with toothstrips. These promote in corporation with the jets of water cutting of the slot walls. During this they are continuously kept clean by the jets of water.
  • said lance can be provided at the lower edge in the middle of the double row spray nozzles with a downwardly extending centering cone extending beyond said nozzles. Said cone just does not reach into the soil affected by the water jets.
  • the means for attaching the sheet comprise several pins spaced from each other against a side face and directed downwardly from this side face, which pins can cooperate with cloth eyelets in the sheet.
  • These cloth eyelets are for instance situated above the inflatable strip and automatically slide from the pins as soon as the injection lance is retracted upwardly and the sheet is held by for instance the inflatable lower side strip or by other suitable means.
  • the means for attaching of the sheet comprise one or more resilient clamps which while clearing the passage orifices for water, can engage U-like around the lower edge of the lance and to which the sheet is attached and which are provided with outwardly barblike extending resilient tongues, which are inclined upwardly as well as directed away from the legs of the U-shaped clamps if these are in the operating position of the lance.
  • the sheet is fixed with the lower edge in the clamps which are themselves clamped to the lower edge of the injection lance. As soon as the lance is retracted, the resilient tongues acting like barbs remain sticking in the ground and hold the clamps and the sheet. The clamps are but lost in this way.
  • a simple arrangement may comprise a pivoting attachment of the downwardly directed pins, which cooperate with the cloth eyelets of the sheet, at a shaft and form them square or bended such that they can abut the side wall of the lance in a closed position or are moved away therefrom in a disconnecting position, so that the cloth eyelets can move downwardly with respect to the lance.
  • a movable crane 1 with crane jib 2 to which crane lance 3 is suspended by the intermediary of a rod 4 at the top end of which a vibration device 5 can be mounted as well as the eyelet 6 for the attachment to the hook of the crane.
  • the sheet 8 coming from a storage reel 7 is guided over a reversing roller 9 and is at the lower side attached at 10 to the lance 3 itself.
  • the storage reel 7 with sheet 8 and the reversing roller 9 can be arranged on the only schematically shown separate apparatus 11, but can also be at the other side and being integrated with the frame of crane 1.
  • Fig. 1 shows the lance at which through line 1.2 water is supplied in a position in which said lance has already penetrated into the ground with some distance.
  • a sheet 13 is present which has been introduced into the soil, which sheet at 14 joins in an overlapping way a previously placed sheet 15.
  • a lance is illustrated at a larger depth with the sheet 8 connected thereto running over roller 9. This sheet 8 is omitted in Fig. 1 for the sake of clearness.
  • Fig. 3 shows the initial position of the apparatus at the introducing of a new sheet, at which the soil is shown in vertical section.
  • This section represents the edge of the already introduced sheet 13 and a bore 16 provided in the area of the edge, said bore contrary to Figs. 1 and 2 is previously provided by the method shown in Fig. 4.
  • Said Fig. 4 shows that with the crane 1, 2 also an usual lance can be lowered by which vertical bores as bore 16 can be produced.
  • These previously produced bores 16 can be of importance for the discharge of the water leaving the lance and the soil loosened by it and further can be of importance for the sealing of the edges of the sheets upon each other.
  • Figs. 5, 6 and 7 the arrangement of the lance is shown, comprising a tube 17 with head 18.
  • This tube is at the under end connected to a flat box 19, which is trapezoidal in side view and consist of two parallel walls 20 and 21 (Figs. 8 and 9), which parallel walls 20 and 21 are welded to the tubes 22, 23 and 24 at the upright side edges and at the lower edge.
  • the upright tubes 22 and 23 have a number of discharging openings schematically shown by the strips 25.
  • These tubes join supply tubes 26 and 27 which are mounted along the big tube 17 and at which at 28, 29 respectively hoses or flexible lines can be connected.
  • the tubes 22 and 23 are in open communication with the lower tube 24, which can also have a direct supply for instance through tube 30 which is illustrated by dotted lines.
  • a downwardly inclined pin 39 is shown, several of which can be mounted distributed across the lower edge of the wall 21 and which stitch into the cloth eyelets 40 of sheet 8. If the injection lance is moved upwardly (indicated at the right hand side in Fig. 8) then the pins 39 withdraw from the eyelets 40.
  • Fig. 9 shows another possibility according to which a shaft 41 is rotatably mounted against the side wall 21, on said shaft several hooks 42 are mounted, which can stitch into the cloth eyelets. Counter clockwise rotation of shaft 41 positions the hooks 42 such that the cloth eyelets are released.
  • Figs. 10 and 11 show another modification for the attachment of the sheet 8.
  • U-shaped resilient clamps 43 At the lance 3 are mounted U-shaped resilient clamps 43 to which the lower edge of the sheet, shown at 44 is attached. These clamps have resilient tongues 45, 46. If, as shown in Fig. 11, the lance is lifted, the tongues 45, 46 enter the soil, whereby the clamps 43 are slid off the injection lance.
  • Fig. 12 shows in top view a screen that is assembled from the sheets 47, 48, 49 and 50. So an unlimited number of sheets can be mounted next to each other and the path can have any desired shape. As shown in Fig. 12, the sheets are mounted with an overlap. After mounting for instance the sheet 47 the next sheet 48 is mounted such that its edge 51 lies on the highest pressure side of sheet 47 indicated by arrow 52. The edge 51 is then forced by ground water pressure against sheet 47 said sheet being supported by the side wall 53 of the slot. At each overlap this method is proceeded. The overlap must have sufficient width for instance of some decimeters.
  • a screen is shown at which the bores 16 shown in Figs. 3 and 4 are used.
  • the sheets 54, 55, 56 stitch with their edges in these bores 16 such that the edges overlap each other. If the bores 16 are filled afterwards with hardening material, the edges are enclosed very well.
  • Fig. 14 the same situation is shown, now however such that the edges of the sheets do not overlap each other, but are spaced from each other. Also in that case the hardening material can bring about a good closure and sealing.
  • Fig. 15 shows sheets 56, 57, 58 which are provided at the side edges with inflatable hollow edge strips 59, 60, 61 and 62.
  • Fig. 16 shows that this method of anchoring can also occur inside a bore 16.
  • Figs. 17, 18 and 19 show an embodiment of the sheet which is on a storage reel 63.
  • This sheet 64 has edge strips 65 and 66 as well as a lower edge strip 67.
  • the edge strip 66 and the lower edge strip 67 are connected to each other.
  • the edge strip 65 is independent of the lower edge strip 67.
  • Such a sheet can for instance be used with the attaching means shown in Fig. 8 or 9.
  • the edge strips 66 and 67 as well as the edge strip lying adjacent to the edge strip 66 and comparable with the edge strip 65 of the preceding sheet are completely filled by pumping with hardening material.
  • the lower edge strip 67 is completely filled by pumping. If the lance is lifted afterwards, the sheet remains at its place because the expanded lower edge strip 67 does not permit displacement.
  • an edge with cloth eyelets 69 is shown, which can cooperate with attachment hooks as hooks 39.
